We divide 990615 by 1
We're looking to find how many times 1 goes into 990615.

On to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 9 away from 9, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

On to step 2:
If we divide 9 by 1, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 9 from 9, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Let's proceed to step 3:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 990.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Moving on to step 4:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 9906.0
If we subtract 6 from 6, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Advancing to step 5:
1 can be fit into 1 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 99061.0
Subtract 1 from 1 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Advancing to step 6:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 990615.0
Subtract 5 from 5 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 990615.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 990615.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 990615.0 and a remainder of 0.0.
